$PECIFICATION forming part of Letters Patent No. 7 09,747, datedSeptember 23, 1902.

Application filed October 30, 1900. Renewed July 11,1902. Serial No.115,218. (No model.)

To all whom, it may concern:

Be it known that I, JOHN J. COOK, a citizen of the United States, and aresident of Colu n1- bus City, in the county of Louisa and State ofIowa, have made a certain new and useful Invention in Devices for Takingup Wear in Worn Axle-Spindles; and I declare the following to be a full,clear, and exact description of the same, such as will enable othersskilled in the art to which it appertains to make and use the invention,reference being bad to the ac companying drawings, and to letters ofreference marked thereon, which form a part of this specification.

Figure 1 is a central longitudinal section showing my invention asapplied. Fig. 2 is a section on the line a; as, Fig. 1. Fig. 3 is adetail View of wear-plate G. Fig. t shows detail views illustrating thejoint between parts B and E. Fig. 5 is a detail view of washer 0 Fig. 6illustrates another form of joint between parts B and E. Fig. 7illustrates two forms of washers c. I

The invention has relation to axle-spindles, and it consists in thenovel construction and combination of parts,as hereinafter set forth.

The object of the invention is to promote the duration of the spindle bytaking up the play due. from wear.

In the accompanying drawings the letter A designates a spindle worn atcertain parts, (indicated at a.)

B represents the spindlenut, and O the shoulder of the spindle.

In the nut B is formed a recess 1), which is of annular form around theopening of the threaded portion, said recess being of larger diameter atits bottom than at its marginal portion.

In the recess b are placed thin washers c, which may be preferablyspring-washers, each washer being cut in such manner as to allow it tospring or be spread open a little in the recess, so that it will holdits position therein. When the spindle becomes a little worn,one ofthese thin washers can be taken out of the recess, and this will allowthe nut to be screwed on the end of the spindle a little in diameter inthe portion toward the shoulder than it is at the end portion.

For nuts already in use I desire to provide a face attachment orrecessed collar, (indicated at 13,) which is secured to the nut by meansof lateral ribs or pins at e e. In this collar the washer-opening ismade with a taperingwall, as hereinbefore set forth in referenceto theannular recess 1) of the nut, or it may have a very small interiormarginal flange f, which will serve to prevent the thin washers fromdropping out of the opening or recess. When these face-collars for thenot are cast of malleable iron, small ribs may be cast on the collar,which will serve instead of the pins 6. These ribs or pins are crowdedinto the flanged face of the nut with the attachment and serve to clenchor secure the latter in position, preventing it from turning in the seatformed by the flange. When the spindle is badly worn, I use an archedwearplate Gon the shoulder portion, this wearplate G being provided witha pin or peg g, which is inserted in a perforation or seat It, made inthe axle, and serves to hold the wear-plate therein, its position beingfurther secured by means of a hook-lug Z, which engages the back of theshoulder portion of the axle. This wear-plate is placed on the upperpart of the spindle-shoulder, and serves to keep the hub of the wheel inits normal position against the bottom or under side of the spindle,thereby providing for proper relation of the parts when the wheel is inaction. This wear-plate is designed to fill the place of the worn parton the shoulder of the spindle, so that it will fit neatly in the backor flanged recess of the boxing.

Instead of using cut washers, the washers may be made entire in annularform, but slightly dished, as shown in Fig. 8, so that When pressed inthe nut-recess they will spread sufficiently to be held in position.

For the large open nuts of wagons, the collar or face attachment may bemade with lugs, asindicated at k,theselugs kextendingatright angles tothe face of the attachment and being designed to engage recesses m,formed in the flange of the nut, in connection with which they may beclenched in position, so as to secure the face attachment and nuttogether. This collar or face attachment is usually a cleft annulus,being so made in order that it may be more readily adjusted to nuts ofvarying size.

In the manner hereinbefore described it is designed to provide fortaking up the wear of spindles principally by means of the adjustablecollar attachment with which the nut is provided, and when the spindleis badly worn the shoulder wear-plate is also used.

I may employ in connection with the leather washer c a washer c ofdished form, which will spring laterally or be put under tension whenthe nut is screwed home upon the spindle. This will maintain a tight fitof the shoulder of the nut against the shoulder of the spindle for agreater length of time without readjustment of the nut and preventsrattling or play of the wheel.

As a substitute for the leather washer c I may employ a washer ofBabbitt metal or brass.

Having described this invention, what I claim, and desire to secure byLetters Patent,

1'. In devices for taking up wear in Worn axle'spindles, the nut havinga recessed inner face provided with a series of removable washerstherein arranged to bear against the shoulder of the spindle, said nuthaving also a second recess in its inner face, and provided with a spring-washer arranged to bear against the shoulder of the boxing,substantially as specified.

2. In a device for taking up wear in axlespindles, the combination withthe nut engaging the end of said spindle, and having a recess in itsinner face, of a face attachment for said nut, having also a recess inits inner face, and the washers in said recesses, arranged to bearagainst shoulders of the spindle and boxing, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN J. COOK.
